"It Must Have Been Love" is actually not a song by Jessica Mauboy, but by the Swedish band Roxette. However, I can still explain the meaning and story behind the song. "It Must Have Been Love" tells the story of a past love that has now ended. The lyrics describe a sense of loneliness and silence as the singer wakes up in a quiet bedroom. The chorus suggests that the relationship was once strong and full of love, but for reasons unknown, it has come to an end. Despite the pain of the breakup, the singer still longs for the past and dreams of being together with their former lover. The lyrics use metaphors to convey the emotional state of the singer. The line "I've turned to water, like a teardrop in your palm" represents vulnerability and feeling emotionally fragile. The song reflects on the longing for that lost love and the realization that it's now gone. Overall, "It Must Have Been Love" explores the feelings of loss, nostalgia, and the struggle of moving on from a failed relationship.
